PRINTING-STAMP.

' To all whom it may concern:

Be it knownthat WQ, ,;.HENRY SCHMIDT and FREDERICK HUBERT, both citizens of the United States, and residents of Elizabeth, in the county of Union and State of New Jersey, have invented a new and Improved PrintingStamp, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide means for altering the operative or service relation of the datingtype and the printing type on the pad; to provide means for varying the imprint of the dating type; and to simplify the construction and arrangement of the elements forming the stamp.

Drawings.-Figure 1 is a longitudinal vertical section taken on the median line of a stamp constructed and arranged in accordance with the present invention; Fig. 2

is a vertical cross section of the same, the section being taken on the median line thereof; Fig. 3 is a side view of a stamp constructed and arranged in accordance with the present invention; Fig. 4 is an end view of the same; Fig. 5 is a detail view showing the printing face or pad of the stamp; Fig.

6 is a detail view showing the supporting shaft for the adjusting rolls.

Description-The stamps having a permanent printing pad 11 and printing belts 12, together with supporting rolls 13 therefor, have heretofore been employed. The belts 12 have welded or otherwise mounted thereon words and figures adapted for mutual arrangement to produce the names or abbreviations of the months of the year, the numerical symbol of the days of the month, and a group of designations for the succeeding years. The figures and letters comprising the numerals and words have been applied to the belts with considerable dissatisfaction, owing to the fact that the thickness of the letters, and occasionally the thickness of the belts on which they are mounted, have considerably varied. To avoid this, the present invention provides an inner frame 14, in which rolls 13 and a platen 15 are supported.

The frame 14 is movable within an outer frame 16, to project the type carried by the belts 12 to a greater or lesser degree beyond the surface of the pad 11. The movement of the frame 14 is guided by a screw 17 and,

by a shaft 18. The shaft 18 is fixedly Specification of Letters Patent.

mounted in the frame 14, and extends through the frame 16, having annular grooves 19 adjacent the ends of the shaft to receive the side edges forming the slots 20 in the frame 16. These slots are best seen in Fig. 4 of the drawings. To permit the insertion and withdrawal of the shaft 18, the slots 20 are provided at the lower end thereof with eyes 21,, sufficiently large to permit the extension of the shaft 18 therethrough. The screw 17 is fixedly mounted in the frame 14:, and is operatively engaged by the threads of a nut 22. The nut 22 is fixedly mounted in a knob handle 23, by

which the stamp is manipulated. The screw infolds the screw 17 When thus construct,

ed, the stamp is equipped for operation in the manner common to the stamps of conventional make.

When the stamp is used, if it be found,

that, owing to the wear of the letters on the pad 11, or owing to the irregularity of the casting of the letters and numerals on the belts 12, the imprint of the words and numerals on said belts is too intense or not sufficiently intense as compared with the imprint of the letters on the pad 11, then the operator, by revolving the handle 23, advances or retracts the frame 1 1 and belts 12 carried thereby, to alter the relation of the type on said belts with the type on the pad 11, to balance the imprint formed by both. The proper registration having been effected, the handle 23 is not thereafter rotated. If, however, in the courseof the operation, it should be desired to increase or diminish the intensity of the imprint of the letters and figures on the belts 12, this is readily effected by revolving the handle 23.

Claims:

1. A printing stamp comprising a main printing pad having permanently mounted thereon printing characters; a plurality of movable pads having printing characters arranged to imprint simultaneously withthe action of said main pad; a frame supporting said movable pads; a frame supporting said main pad; a feed screw operatively connecting said frames to alter and fix the operating positions thereof; and an operating handle for said pad, said handle being operatively connected with said screw.

2. A printing stamp comprising a main printing pad having permanently mounted thereon printing characters; a plurality of movable pads having printing characters arranged to imprint simultaneously with the action of said main pad and subject to the same pressure; a frame supporting, said movable pads; a frame supporting said main pad; a feed screw operatively connecting said frames to alter definitely'th' operating position thereof; yielding means operable to normally separate f1'ames;"and compressible'by' the manipulation said Copies of this patent may be obtained for five cents each, by Washlngtonffl 0.

sOlfBW; an operating handle for said screw, extending beyond said frames; and means operatiyely connecting said framesto guide theinovmentthereof. 4' In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
